7 . Colonoscopy and severe hematochezia
نویسنده
چکیده
Hematochezia is the passage of bright red blood or maroon colored blood, with or without clots, per rectum. Most often hematochezia is low grade and self limited and does not require hospitalization or urgent intervention. Such patients can be managed in an outpatient setting. A smaller group of patients experience severe hematochezia and require hospitalization because of the volume of blood loss or symptoms due to severe anaemia or comorbidity[1,2]. In addition, another group of severely ill patients will develop severe hematochezia while in the hospital for other medical or surgical conditions. These latter two groups require a systematic and expeditious approach to their resuscitation, preparation, diagnosis, and treatment. For more than a decade, our CURE-UCLA Hemostasis Group has recommended an aggressive diagnostic approach with preparation of the patient with oral purge followed by urgent colonoscopy for diagnosis and treatment. This approach is similar to that used for patients with severe UGI hemorrhage. This approach changes outcomes of patients, particularly for those with severe or persistent hematochezia[1,2].

This study investigates outcomes and possible necessity for further work up in cases of hematochezia with normal colonoscopy.

Lower gastrointestinal bleeding (LGIB) is defined as acute or chronic abnormal blood loss distal to the ligament of Treitz. The incidence of LGIB is only one fifth of that of the upper gastrointestinal tract and is estimated to be 21 to 27 cases per 100,000 adults per year.
